I ing 14, does not tend to produce abinding of the parts during rotation ot the body. The thrust is also exerted along member. ysteam. tube 6, interiorly of packing material 11, so that there is no tendency to disarrange or displace the packing material. Because of the position ofthel bearing 14,it may bev inspected 'and lubricated through the spaces existing between the longitudinal frame .memberslS of the body member 2. Even `though the periphery of the body member weremade cont1nuous access to bearing 14, for inspection and lubrication of the same, might be obtained by merely removing the `cap orcover plate 16.: It will also be' noted that the bearing, .while constituting airintimatefpart of the pipe joint structure, isV

`wholly removedfrona ,the steamE zone thereof.

I twill be readily observed that the Siphoning tube 9 may be withdrawn-from its. position within steam tube Gland body 'member 1 without removing either the steam tube or lthe body member '1, or disturbing the pack- Y ing material y11. The packing material 1.1

suitable instrument mayi be inserted inthe intervals between the'longitudinal frame members- .18 for the purpose "of picking out theold` packing material andpushingfresh v' Y packing material into the seat 10.V Y

Itwillbe further notedthat the packing ,materialfot' the joint is not subjected to great thrustin force.` Y There is no Apossibility that beblownfrom Ythe pipe joint, because ofimproper fasteningiof the bolts 13 or excessive i `Apressure within thepipe joint and hot roll.

What Iclaim is:

. 1. In a revoluble pipe-joint` y for steamV heated rolls, a body member having a peripheral portionwith an openingthereth for a fixed steaminlet-tube anci'a seat or packing material insaidiopening, a Yflange integral with and arranged on one side of said peripheral portion to be fixed against the trunnion of a hollow roll, spaced frame membersv integral with' and extending on the other side of said-.peripheral portion,y an end member secured tothe extending frame` members,v acollar on said steam'inlet'tube and means between said collar ,and Vsaid end member for vwithstanding thrust which tends to.

2.
